Detailed description of the invention
Fig. 1 is the logical procedure diagram of meter reading channel data acquisition tasks of the invention.
Specific embodiment
With reference to the accompanying drawing, embodiments of the present invention are illustrated.The data of plant stand electric energy acquisition terminal are adopted automatically
Collect implementation method, comprising the following steps:
Step 1, addition needs to acquire the electric energy meter of data in plant stand electric energy acquisition terminal, since plant stand electric flux is adopted
The type and quantity for the electric energy meter that collection terminal is managed may be relatively more, in order not to allow the parameter of these electric energy meters excessively to disperse,
It is not to be managed as unit of electric energy meter, but managed as unit of the meter reading channel of electric energy meter access acquisition terminal
, there is a unique corresponding meter reading channel number in each meter reading channel.The parameter of each electric energy meter in one meter reading channel
Data structure is managed by meter reading channel design chained list again.In order to search out the electric energy meter in the meter reading channel
Parameter, we provide a structure chained list for each meter reading channel, the argument structure of the electric energy meter of addition are added to its institute
Behind the structure chained list in the meter reading channel of access.Meter reading channel design chained list establishes meter reading channel catalogue while foundation, use
In the storage file catalogue of subsequent acquisition data.After being updated based on the structure chained list that meter reading channel is unit, plant stand electric energy
The electric energy meter accessed in amount acquisition terminal is installed.
Carry out the peace of meter specification when electric energy meter is installed according to the meter specification parameter in parameters of electric energy meter structural body first
Dress calls meter specification to install function, to the acquisition process letter in parameters of electric energy meter structural body in meter specification installation function
Number pointer carries out assignment.
According to meter reading channel number parameter decision meter reading channel in parameters of electric energy meter structural body in electric energy meter installation process
It is whether enabled, if meter reading channel is to enable for the first time, opens meter reading channel and create meter reading channel binary signal
Amount.If meter reading channel is enabled, last meter parameter is updated to current parameters of electric energy meter in meter reading channel design chained list
And the electric energy meter quantity in meter reading channel adds one；Current electric energy meter is updated to meter reading channel design in parameters of electric energy meter structural body
Last electric energy meter in chained list, next electric energy meter is sky, current electricity in parameters of electric energy meter structural body in parameters of electric energy meter structural body
Next electric energy meter in energy table structure is updated to current electric energy meter.
Meter reading channel binary semaphore creates when meter reading channel enables for the first time in electric energy meter installation process, in meter reading
This semaphore is successfully obtained in the acquisition tasks of channel indicates the enabled success of meter reading channel, can carry out subsequent electric energy meter number
According to timing acquiring operation processing.
Electric energy meter data acquisition is initiated in step 2, plant stand electric energy acquisition terminal as unit of meter reading channel and handles task,
Electric energy meter data acquisition processing task will not exit after initiating for the first time, this task is by memory-resident, until in the meter reading channel
All electric energy meters are deleted and finish backed off after random.
It in electric energy meter data acquisition processing task, can all judge whether the data of acquisition in need every second, judge
Foundation is preset automatic data collection time interval.The interval of this second is by distributing for each meter reading channel
The control of one binary signal amount, in the second that real-time clock provides interrupts, the primary semaphore can be discharged each second, and
The binary signal amount that can be provided by system in data acquisition process task obtains function and directly acquires the semaphore.Also
Say in plain data acquisition process task it is to hang up, only when real-time clock interrupt service routine discharges binary signal
Amount, just will do it the acquisition and processing of electric energy meter data.So the acquisition interval time of timing acquiring can set since one second
It sets.
Step 3, when meeting the requirements the time of Timing Data Acquisition, just carry out meter reading channel in electric energy meter corresponding data
Acquisition operation.The data element in parameters of electric energy meter structural body is called, data type is structural body, defines letter in structural body
Number pointer.It is realized in module in specification, defines acquisition function and by acquisition function assignment in parameters of electric energy meter structural body
Acquire function data element.It acquires and calls universal data collection function in function, this acquisition function is a structural body.
The acquisition power function structural body of definition is passed in the form of parameter in universal data collection function, in this acquisition
Appearance is divided into six parts: generated energy acquisition, requirement/time of origin acquisition, instantaneous flow acquisition, rate of qualified voltage acquisition, logout
Acquisition, state alarm collection, this six part provide an acquisition function by electric energy meter specification respectively.More convenient pair of difference in this way
The equipment of specification is called from stipulations storehouse, and carries out the initialization in meter reading channel to acquisition meter reading channel according to device parameter
Operation.Data conversion collected from electric energy meter at the format of Uniform provisions, it is put into buffer area, so as in store tasks
It saves.
As shown in Figure 1, being the logical procedure diagram of meter reading channel data acquisition tasks of the invention, comprising the following steps:
2.1, judge whether electric energy meter quantity is greater than 0 in meter reading channel, if it is, turn in next step, if not, turn 2.10；
2.2, judge whether successfully to obtain meter reading channel binary semaphore, if it is, turn in next step, if not, turn
2.10；
2.3, judge whether first electric energy meter pointer parameter effective in meter reading channel, if it is, turn in next step, if
It is no, turn 2.8；
2.4, judge whether current time arrives the automatic data collection time, if it is, turn in next step, if not, turn 2.7；
2.5, electric energy meter device parameter is obtained, meter reading channel is initialized and obtains copy reading data information；
2.6, data acquisition process, data acquisition after according in parameters of electric energy meter structure to the decimal digits of data and unit
Be set for the processing of data, and be put into appointed buffer；
2.7, read chained list in next parameters of electric energy meter pointer, determine whether effectively, if it is, turn in next step, if
It is no, turn 2.5；
2.8, judge whether initiate store tasks, if it is, turn in next step, if not, turn 2.1；
2.9, judge initiate deposit whether several tasks succeed, if not, turn in next step, if it is, turn 2.1；
2.10, terminate meter reading channel data acquisition tasks and exit.
